Those look like Ontarios to me. They are probably the heaviest of the regular latin style machetes. The Tramontinas are the lightest I have used. The Collins, Cold Steels, Condors, and Imacasas are in between. In any blade over 18", I'll go with the Tramontina because I can swing it longer. But heck, I'm old. A younger man might prefer one of the heavier ones.
